SPECIFICATION forming part of Letters Patent No. 483,957, dated October4,1892. Application filed November 5, 1891. Serial No. 410.990- (Nomodel.)

To all whom it may concern:

Be it-known that I, JONATHAN GODFREY, a citizen of theUnited States,residing at Bridgeport, in the county'of Fairfield and State ofConnecticut, have invented certain new and useful'lmprovements inMachines for Making Paper Boxes and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to certain new and useful improvements in machinesfor manufacturing boxes from paste or straw board, and for a full andcomplete understanding of my invention I would refer to the accompanyingdrawings, forming a part of this specification, and in which- Figure 1is a front elevation, partly in section, of my newly-invented machine;Fig. 2, a detail sectional front elevation showing particularly theoperation of the devices Whereby the boxes are forced upon and off fromthe traveling apron; Fig. 3, a detail side elevation, the drying-drumbeing in section; Fig. 4, a detail section at the line on a: of Fig. 1;and Fig. 5, a view similar to Fig. 1,but illustrating the operativeparts in their relative positions immediately after a, blank has beencut.

Similar numbers and letters denote like parts in the several figures ofthe drawings.

1 is the bed of an ordinary power-press; 2, the uprights risingtherefrom; 3, the shaft, and 4the gate guided within the upright andactuated from the eccentrics 5 6 on the shaft in the usual manner.

7 is an independent gate adapted to slide freely in bearings at thecenter of the gate 4, said gate 7 being actuated from the eccentric 8 onthe shaft 3.

9 is a yoke, which is secured to opposite sides of the gate 4 andextends beneath the gate 7, and 10 is the blanking-die secured to thebottom of said yoke.

11 is the shaping-die which cups up the boxes and depends from the gate7. The die 10 is perforated to admit the die 11 therethrough, for thepurpose presently explained.

12 is a block secured on the bedl and havin g a chamber 13, which leadsinto a chute 14,

which latter is secured within the bed inany suitable manner.

15 is the die-block mounted on the block 12 andchambered to afford thecomplements of the dies 10 11.

16 is a drying-drum, which is located below the bed of the press and issupported in'any suitable manner, as by foot-blocks 17.

18 is the hot-air inlet and 19 the outlet, re spectively located at thetop and bottom of the drum. 7

20 is a shaft journaled in the rear end of the drum and having a pulley21, mounted thereon.

,22 is a hanger secured to the bed 1, and 23 a shaft journaled in saidhanger and having mountedthereon a pulley 24.-

25 is an endless apron around the pulleys 21 24, said apron havingsecured thereon at regular intervals perforated drying forms or blocks26. The forward end of the drum has openings 27 to admit'the apron andblocks during their travel.

28 is a short shaft journaled in the hanger 'j 5 22 and having thereon amutilated gear-wheel 29, which meshes with a spur 30 on the shaft 23.

31 is a vertical shaft journaled in brackets 32 33 at the side of one ofthe uprights and having at the top and bottom bevel-gears 34 8o 35,which mesh, respectively, with bevel-gears 36 37 on the shafts 3 and 28.

From the foregoing it will be clear that rotary motion is imparted tothe pulley 24 from the shaft of the press. It also will be clear thatthe gear 29 will constantly revolve, but that the spur 30 will revolveintermittingly, owing to the mutilation of the gear 29. It is necessarythat the spur 30 should be stationary at certain predetermined times, inorder that the boxes may be deposited on and driven off from the blockson the apron. As fast as the boxes are stripped from the shaping-diethey fall within the chute and are impelled down the latter by anair-blast, which enters by a pipe 38, which latter leads into the upperend of the chute. This blast is not abso lutely necessary, since theboxes will generally slide down the chute by gravity, but thev are sovery light that I prefer to use the air- :00 blast as a sure means fordriving the boxes. The bottom of the chute terminates directly over theapron, and is at that point open, as seen at 40; but two slight springs39 are secured to opposite sides of the chute and extend beneath theopening in the latter to afford ledges, on which the lowermost box marest, as shown at Figs. 1 and 4.

41 is a' plunger guided within a housing 42, extending upward from thechute immediately above the opening 40, and 43 is a lever pivoted to thehanger 22 and loosely connected at 44 to the top of the plunger 41.

25 is a lever pivoted to the hanger 22 and having a stud46 dependingfrom its inner end immediately over the lower plane of the apron. a

47 is a vertical rod depending from a strap 48 around an eccentric (notshown) on the shaft 3, and to this rod the outer ends of the levers 4345 are pivoted, so that it will be readily understood that the verticalreciprocation of the rod 47 will effect a similar reciprocation of theplunger 41 and stud 46. The timing of the gears 29 30 and the rod 47 issuch that when the travel of the apron is arrested the plunger and studwill be in their elevated positions and a block 26 on the upper plane ofthe apron will have been brought immediately beneath the plunger, whilea similar block on the lower plane of the apron will have been broughtimmediately beneath the stud, as will be readily understood by referenceto Fig. 2. The apron will remain stationary until the rod 47 has beenelevated to depress the plunger and stud.

The operation of myimprovement is as follows: The pasteboard in dampenedcondition is fed beneath the dies 1O 11 on the block 15. The die 10operates in advance of the die 11 to cut out a blank, as shown at Fig.5, and the die 11 afterward descends to shape the blank into cup form,as shown at Fig. 2. When the die 11 ascends, the boxes will stripthemselves from said die by impact against the bottom of the block 15,and will fall within the chute and be driven down the latter by theair-blast. Referring to Fig. 1, I will designate the lowermost box inthe chute by the letter a and the succeeding box by the letter I). Thebox a is supported by springs 39, as shown particularly at Fig. 4, andwhen the plunger 41 descends it will force said box down and over theblock 26 immediately thereunder. Simultaneous with this action of theplunger the stud 46 will be driven through the block 26 beneath it andwillstrip the box therefrom. The blocks 26 will during the travel of theapron be successively brought beneath the plunger 41 for thereciprocation of the boxes, thence carried through the drying-drum,andfinally brought in succession beneath the stud 46, whereby the boxes arestripped and allowed to drop into any suitable receptacle.

\Vhen the box a has been deposited on the apron and the plunger has beenreturned to normal position, the box I) will be driven into the end ofthe chute by the air-blast and will be forced down upon the apron by thenext descent of said plunger.

The drying of the boxes while on a block gives very good results in thatthe sides of the boxes will not become warped as would be the case weresaid bo'xes simply deposited on a drying-shelf.

Heretofore in the manufacture of these boxes they have in some instancesbeen deposited on drying-shelves after shaping by dies; also, in someinstances they have after being shaped been forced through an elongatedhot tube.

It has been demonstrated that these boxes madefromdamppasteboard,ifdriedonshelves or in mass, will warp out of shape, thereby necessitating afinal shaping operation. Again, if after they are struck up by the diessaid boxes are forced through an elongated hot tube they will be butimperfectly dried, while the operation of stripping them from the formon which they are forced prior to being driven through said tubefrequently causes a distortion of the boxes. There is, however, anadditional objection to the foreing of the boxes through a hot tube, dueto the fact that the sides of the boxes are rendered thinner, andconsequently are drawn out by the compression between the form and tube,thus seriously affecting the uniformity of the boxes. The gist of mypresent invention rests in the broad idea of automatically forcing theboxes on and off forms preparatory to drying and not in any particularadaptation of chute or traveling apron.

My invention is applicable to the manufacture of round, square, or anyother shape of box.

I claim- 1. In a machine for making paper boxes, the combination, withsuitable dies for forming the boxes from a moist strip of paste or strawboard, of a drying-drum, an endless apron traveling in said drum andprovided with blocks for the reception of the moist boxes, means fordepositing said boxes successively upon said blocks, and means forstripping said boxes from said blocks, substantially as set forth.

2. In a machine for making paper boxes, the combination of suitable diesfor forming the boxes from moist pasteboard, drying-forms beneath saiddies, means for forcing said boxes while moist upon said forms prior todrying, and means for stripping said boxes from said forms after thecompletion of the drying, substantially as set forth.

3. In a machine for making paper boxes from moist pasteboard, thecombination, with suitable dies whereby the boxes are shaped, ofdrying-forms, means for automatically bringing said forms to apredetermined position,instrumentalitiesfordepositingtheboxes whilemoist on said forms preparatory to drying,and instrumentalities forstripping said boxes from said forms after drying, substantially as setforth.

the reciprocatory plunger whereby the boxes are forced upon said forms,and the reciprocatory stud whereby the boxes are stripped, I 5 from saidforms, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
